This paper presents an analysis of sentences with language units jeszcze (yet, still) and już (already, yet), contained in textbooks for teaching Polish as a foreign language at levels A1 and A2. The aim of the analysis was to distinguish the meanings of these units. At the lowest levels of command of Polish, analogy particles jeszcze and już and temporal exponents jeszcze and już are the most common units. This paper also proposes preliminary forms of definitions adapted to the pre-intermediate level of command of Polish. [ABSTRACT FROM AUTHOR]

Selpercatinib, a RET kinase inhibitor, is an effective treatment for patients with medullary thyroid cancer with RET mutations. In this paper, we present the case of a 62-year-old man with ectopic Cushing's syndrome due to medullary thyroid cancer who received treatment with selpercatinib. Six months later, all the cushingoid features had resolved, and s-calcitonin had decreased from 580 pmol/L to 3.5 pmol/L (normal < 3). After further 6 months, s-calcitonin had normalized (1.5 pmol/L), and radiological evaluation showed a profound tumour volume reduction. We are aware of two other cases where treatment with selpercatinib has also been successful. Thus, selpercatinib may be a promising treatment alternative in patients with ectopic Cushing's syndrome due to medullary thyroid cancer, especially when other treatment options are ineffective or not tolerated.

Some new cases of anomalies in wild Bufotes viridis from Western Poland are presented together with a discussion of their potential causes and a comparison with similar cases from the literature. The anomalies in question are color aberrations (pre- and postmetamorphic) and developmental pathologies (pre-metamorphic). The color anomalies include an ochre patch in a juvenile, leucism and albinism in both tadpoles and juvenile individuals. Developmental pathologies described in this paper include gigantism, edema, curvature of tail, and asymmetric bodies. [ABSTRACT FROM AUTHOR]
